GEORGE VAN WAGENEN, OF NEW YORK, N. Y.

. STOVE.

SPECIFICATION forming partof Letters Patent No. 372,831, dated November8, 1887.

Application filed March 4, 1887.

My invention more particularly relates to stoves which may beemployed inheating cars or boats, and which are so constructed as to prevent theescape from confinement of the fire in case the stove shall by anyaccident be overturned or injured.

In my application for Letters Patent, Serial No. 228,0l5, filed February18, 1887, I have shown a stove formed of two or more shells'or casingssurrounding one another and separated by air'spaces, which are bridgedover by braces or pins in order to hold the shells or casings at therequisite distance apart in case of accident. That stove has at the topa smoke-outlet, which is formed by coincident openings in the severalshells or casings, each protected by a guard consisting of parallel barsarranged in close proximity to each other, so as to form narrow spacesbetween them, and I have also shown a cleaner or scraper, which, byreciprocating movement transversely to the length of the bars, serves tokeep clear the spaces between them.

Important objects of my present invention are to provide for morereadily and thoroughly'cleaning a grating composed of parallel bars, andalso to give the pins or studs which constitute braces supporting theshells or casings,and which are fixed in one shell or casing, a broaderand more stable bearing upon the other shell or casing, so that thestuds or braces will not be liable to be bent over laterally in case thestove is subjected to a crushing blow or force, but will maintain theirnormal position at right angles to the shells or casings between whichthey extend.

In carrying out my invention I construct the scraper or cleaner, wherebythe guards of the smoke-outlet are kept clean, with teeth or projectionstoenter between the bars-forming the guards, and adapting the scraper orcleaner to be slid lengthwise of the bars. I also construct the braceswhich bridge over the airspaces between the two shells or casings in theform of posts or studs,which are secured each Serial .No. 230,153. (Nomodel.)

in one shell or casing, and have a broad end or foot for bearing againstthe adjacent shell or casing.

In the accompanying drawings, Figure 1 is a sectional elevation of theupper portion of a stove, which is very similar to that forming thesubject of my aforesaid application and in which my present invention isembodied. Fig.

2 is a transverse section of one of the series of bars which guard thesmoke'outlet, also showing the cleaner or'scraper having teeth orprojections for entering between these bars, and which is designed to bereciprocated lengthwise of the bars; and Fig. 3 is a horizontal sectionof a portion of the concentric shells forming the stove-body andillustrating my improved braces or posts bridging over the spacesbetween these shells or casings, the said figure being upon a largerscale than Figs. 1 and 2.

Similar letters of reference designate corresponding parts in theseveral figures.

In this example of my invention the stove is formed by shells or casingsA A A which surround one another, and are closed by top plates, B B BThe inner shell or casing, A, which constitutes the fire-pot, may be ofcast or wrought iron or steel, and I prefer to make the outer shells orcasings, A A of steel or iron plate. The casings or cylindric shells A AA and their several top plates, 13 B B are maintained at a fixeddistance apart, in order to form air-spaces b 12 between said shells orcasings and between their plates B B 13*. I have represented the severalshells or casings as maintained at proper distances apart by posts orbraces G, which, as here represented, are secured by riveting orotherwise at oneend, c, in the shell or casing, and have at the otherend each a broad foot or end portion, 0, which has a broad bearing uponthe adjacent shell or casing. When the braces or posts 0 are thusconstructed, each with a broad foot or end for bearing on the shell orcasing adjacent to that in which a post or brace is secured, there is noliability of the post or braces being upset or bent over laterally incaseof the stove being subjected to a crushing force or blow, as therewould be if the posts or braces were of the same small diameter to theirhearing ends and were destitute of the broad end portions or feet, 0,just described.

In each of the top plates, B B B I have represented a smoke outlet orhole, d, and these several plates are connected by thimbles or flangeddistancepieces D, whereby they are connected at proper distances apartand whereby the smoke-outlet d in each plate is surrounded. The lowerflange of each distance-piece D may be secured by riveting, as at d, toone of the top plates, and the upper flange of such distance-piece maybe detachably secured to another of said top plates by bolts d, orotherwise. The smoke-outlet, which is formed by the coincident openingsdin the several top plates, terminates in a nipple or projection, D,adapted to receive a smoke-pipe, and each of the openings at is guardedor protected by a grating composed of parallel bars (1 arranged in closeproximity to each other and forming spaces between them. I have shown,for keeping clear each guard, a scraper or cleaner, d, which may beoperated by a handle, d, and which has its edge serrated or providedwith teeth or projections, as shown in Fig. 2, to enter the spacesbetween the bars (P and keep them clear of ashes and soot. The scraperor cleaner (1, when constructed with teeth or projections, as described,is to be reciprocated or slid lengthwise of the bars (2 in order to keepclear the spaces between them.

To prevent the escape of small pieces of coal or hot ashes in case ofthe stove being overturned, I arrange within the stove, and at a littledistance below the top plate B, in which is the first outlet-hole d, ashield or plate, E, which is imperforate and larger in horizontal areathan the smoke-outlet d. The shield or plate E is at alittle distancebelow the smokeoutlet, and prevents small scraps of red-hot coal orashes from escaping through the smoke outlet in case of the stove beingoverturned. The plate E is hung upon studs 0, provided at the ends withheads and very loosely-fitting holes e 0, formed in the shield or plateE and in the top plate B. The large heads of these pins or studs e holdthe plate or shield E in the position shown in Fig. 1; but they fit soloosely in their holes 0 c that in case of the v stove being overturnedthe shield or plate E will by gravity be caused to close tightly downupon the smoke-outlet d, and absolutely prevent the escape through thegratings d of any particles of red-hot coal or ashes.

I only seek to cover herein a brace or stud, O, broadened at one end,the other end being secured to the shell or jacket; and I do not claimherein a brace or stud broadened as well at the end which is secured tothe shell or jacket as at the free end, because such a claim is includedin my application Serial No. 231,382, filed March 18, 1887.

What I claim as my invention, and dcsi re to secure by Letters Patent,is

1. The combination, with the stove-top having its smoke-outletprotectedby aguard composed of parallel bars, of a scraper or cleaner havingteeth or projections which enter between the bars and adapted to bereciprocated over the guard in a direction lengthwise of the bars,substantially as herein described.

2. The combination, in a stove, of two or more shells or casings; onesurrounding another and forming air-spaces between them, and bracesbridging over such air-spaces, and each consisting of posts or studssecured in one shell or casing, and having a broad end or foot forbearing against the adjacent shell or casing, substantially as hereindescribed.
